The term median refers to an average value indicated by the middle number or numbers in a series. It can be different from the "mean", which is the average value found by adding the numbers and dividing.
Where there is an odd number of values, the median is the central (middle) value.
For example, in the set [ 1, 2, 7, 50, 100 ] the median value is 7. There will be as many values less than the median as there are greater than the median. (if you have duplicate values, more than one may be equal to the median)
Where there is an even number of values, the median is the mean (average) of the two central values. For example, in the set [ 1, 2, 7, 9, 50, 100 ], there are two central values, 7 and 9. The median would be 8, and again there will be as many values less than the median as there are greater than the median.
To find the median : put your numbers in order by their value, and count the number of values. Divide the number of values by two to locate the center value or values. Where the number of values is even, add and average the two in the middle.
Example : values [ 27, 18, 3, 99, 55, 1, 16 ]
Ordered set : [ 1, 3, 16, 18, 27, 55, 99 ]
Median : 18

The median is the central value in an ordered list of numbers. If there is an even number of numbers in the set, the median is the average of the middle two.
Median in math is a term that is used when you are looking for the mid point.
The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two.
Ex. (10, 17, 20, 45, 68)
The median is 20.
